How to show and hide events in Fullcalendar v5
问题 I am trying to show and hide events according to extraparam value. However it does not work as expected. Any advice would be appreciated. js: document.addEventListener('DOMContentLoaded', function() { var calendarEl = document.getElementById('calendar'); var calendar = new FullCalendar.Calendar(calendarEl, { now: '2020-07-11', scrollTime: '00:00', aspectRatio: 1.8, headerToolbar: { left: 'today prev,next', center: 'title', right: 'dayGridMonth,timeGridWeek,timeGridDay,listMonth' },
